Good gaming and editing PC suggestions.

Hello,
I'm working on my first build and I decided to go with a gaming/editing PC I've been apart of the PC gaming scene for a while but this time I want to have a computer specifically designed for gaming. This is what I have so far: http://pcpartpicker.com/p/B99B
However I'm fully open to suggestions I want to keep the build under $1200 for everything excluding the monitor. I plan to be doing some overclocking on my cpu and bring it up to 4.0 GHz as well as overclocking my graphics card once I learn how to. This is going to be a really important thing for me so I want to get my monies worth. Being 15 it's not the easiest to get money. Thank you!
